Galley-Klimaanlage Galley Air conditioning
Die vorliegende Erfindung betrifft eine Galley für ein Fahr zeug, wobei die Galley einen Anschluss für die thermische An bindung der Galley an eine Fahrzeug-Klimaanlage des Fahrzeugs umfasst. Die Erfindung betrifft auch ein Fahrzeug, insbeson dere ein Schienenfahrzeug, umfassend eine solche Galley. The present invention relates to a galley for a driving convincing, the Galley comprises a connection for the thermal connection of the galley to a vehicle air conditioning system of the vehicle. The invention also relates to a vehicle, in particular a rail vehicle, comprising such a galley.
Ein Schienenfahrzeug mit einer derartigen Galley ist bei spielsweise aus EP 3 202 634 Al bekannt. A rail vehicle with such a galley is known for example from EP 3 202 634 A1.
Im Folgenden wird die Erfindung teilweise in Hinblick auf ei ne Galley eines Schienenfahrzeugs beschrieben, es ist jedoch auch vorstellbar die Erfindung in anderen Fahrzeugen mit ei ner Galley, wie beispielsweise in einem Flugzeug oder einem Schiff zu verwenden. Als Galley ist hier also insbesondere eine Bordküche eines Luft-, Schienen- oder Wasserfahrzeugs, wie eines Flugzeugs, Zugs oder Schiffs, zu verstehen. In the following, the invention will be described in part with respect to a galley of a rail vehicle, but it is also conceivable to use the invention in other vehicles with egg ner Galley, such as in an airplane or a ship. As Galley is thus to be understood in particular a galley of an air, rail or watercraft, such as an aircraft, train or ship.
Aufgrund der begrenzten Leistung von Fahrzeug-Klimaanlagen, insbesondere Fahrgast-Klimaanlagen in Schienenfahrzeugen, die auch die Galley mit Kaltluft versorgen und der innerhalb der Galley verbauten Wärmequellen (Ofen, Kaffeemaschine, etc.), heizt sich die Galley insbesondere im Sommer stark auf. Due to the limited power of vehicle air conditioning systems, especially passenger air conditioners in rail vehicles, which also supply the Galley with cold air and built in the galley heat sources (oven, coffee maker, etc.), the Galley heats up especially in the summer.
Über den Anschluss an die Fahrzeug-Klimaanlage wird üblicher weise warme Luft aus dem Bereich der Wärmequellen der Galley beispielsweise über eine Dunstabzugshaube abgesaugt und zu einem Fortluftgerät der Fahrzeug-Klimaanlage transportiert. Dort wird die Luft dann aus dem Schienenfahrzeug transpor tiert. Im Druckschutzfall, z. B. bei Tunneleinfahrten eines Schienenfahrzeugs, wird das Fortluftgerät jedoch abgeschal tet. Zudem reicht der Luftaustausch auch ohne diese Ausfall zeiten in der Regel für die Galley nicht aus, sodass sich in der Galley Temperaturen von über 30 °C einstellen können. Gleichzeitig sind die räumlichen Ausmaße einer Galley eines Fahrzeugs begrenzt und es ist regelmäßig nicht wünschenswert, den freien Raum der Galley zu verringern, um beispielsweise eine eigenständige sekundäre Klimaanlage für die Galley vor zusehen. Weiterhin würde eine eigenständige sekundäre Klima anlage für die Galley auch die Kosten der Galley deutlich er höhen . About the connection to the vehicle air conditioning is usually sucked warm air from the field of heat sources Galley, for example, via an extractor hood and transported to a exhaust air device of the vehicle air conditioning. There, the air is then transported from the rail vehicle. In the pressure protection case, z. B. at tunnel entrances of a rail vehicle, the exhaust air device is switched off, however. In addition, the air exchange is sufficient even without these downtime usually for the galley, so that can set in the galley temperatures of about 30 ° C. At the same time, the spatial dimensions of a galley of a vehicle are limited and it is regularly not desirable to reduce the free space of the galley, for example, to provide a separate secondary air conditioning system for the galley. Furthermore, a separate secondary air conditioning system for the Galley would also significantly increase the costs of the Galley.
Die Aufgabe besteht daher darin, einer Galley eine bessere Klimatisierung zur Verfügung zu stellen, ohne den freien Raum der Galley deutlich zu verringern. The task is therefore to provide a galley better air conditioning available without significantly reducing the free space of the galley.
Erfindungsgemäß wird eine Galley für ein Fahrzeug der ein gangs genannten Art zur Verfügung gestellt, welche einen An schluss für die thermische Anbindung der Galley an eine Fahr zeug-Klimaanlage des Fahrzeugs sowie eine Galley-Kälteanlage zur Versorgung von lokalen Kühlstellen in der Galley umfasst. Die Galley umfasst ferner eine Galley-Klimaanlage, die von der Fahrzeug-Klimaanlage getrennt ist, wobei die Galley- Klimaanlage von der Galley-Kälteanlage mit Kühlmittel ver sorgt wird. According to the invention, a galley for a vehicle of the initially mentioned type is made available, which includes a connection for the thermal connection of the galley to a driving tool air conditioning system of the vehicle and a galley refrigeration system for supplying local cooling points in the galley. The galley further includes a galley air conditioner that is separate from the vehicle air conditioner, the galley air conditioner being provided with coolant by the galley refrigeration system.
Die erfindungsgemäße Lösung hat den Vorteil, dass die Galley- Klimaanlage eine bessere Klimatisierung der Galley erlaubt, ohne das eine eigenständige sekundäre Galley-Klimaanlage mit eigenständiger Kühlmittelversorgung notwendig ist, da das ge kühlte Kühlmittel bereits von der Galley-Kälteanlage bereit gestellt wird. Bevorzugt ist die Galley-Klimaanlage als zu sätzlicher Kühlkreislauf innerhalb der Galley realisiert be ziehungsweise umfasst die Galley-Klimaanlage einen zusätzli chen Kühlkreislauf innerhalb der Galley. The solution according to the invention has the advantage that the Galley- allows a better air conditioning of the galley, without the independent secondary Galley air conditioning with independent coolant supply is necessary because the ge cooled coolant is already provided by the Galley refrigeration system. Preferably, the galley air conditioner is implemented as an additional cooling circuit within the galley, and the galley air conditioning system comprises an additional cooling circuit within the galley.
Galleys verfügen häufig über eine Galley-Kälteanlage, um meh rere lokale Kühlstellen, zum Beispiel Kühlschränke oder Tief kühlfächer zentral mit Kühlmittel zu versorgen. Dies spart Platz und erlaubt es, die Kühlstellen fest im Boden und/oder der Wand der Galley zu verbauen. Es wird also die Kühlkapazi tät der Galley-Kälteanlage mitverwendet, um die Galley- Klimaanlage zu betreiben. Die Galley-Klimaanlage nimmt daher weniger Platz in Anspruch und erhöht die Kosten der Galley weniger als eine eigenständige sekundäre Galley-Klimaanlage. Moderne Kühlstellen weisen eine so wirksame thermische Isola tion auf, dass es üblicherweise nur notwendig ist, diese für einen Bruchteil der Betriebszeit aktiv zu kühlen. Weiterhin müssen auch meistens nicht alle Kühlstellen gleichzeitig mit Kühlmittel versorgt werden. Es steht also regelmäßig zumin dest ein Teil der Kühlleistung der Galley-Kälteanlage unge nutzt zur Verfügung. Galleys often have a Galley refrigeration system to centrally supply multiple local refrigerators, such as refrigerators or deep freezers, with coolant. This saves space and makes it possible to obstruct the refrigeration points firmly in the floor and / or the wall of the galley. Thus, the cooling capacity of the Galley refrigeration system is used to control the Galley To operate air conditioning. The Galley Air Conditioner therefore takes up less space and increases the cost of the Galley less than a stand-alone secondary Galley Air Conditioner. Modern cooling points have such an effective thermal Isola tion that it is usually only necessary to actively cool them for a fraction of the operating time. Furthermore, not all cooling points usually need to be supplied with coolant at the same time. It is thus regularly at least part of the cooling capacity of the Galley refrigeration plant unge uses available.
Die Temperatur innerhalb der Galley kann mit der erfindungs gemäßen Lösung reduziert werden, wodurch sich verbesserte Ar beitsbedingungen für das Galley Personal ergeben. Dazu wird die ohnehin für lokale Kühlstellen installierte beziehungs weise vorgesehene Kälteleistung verwendet. The temperature within the galley can be reduced with the solution according to the invention, resulting in improved Ar beitsbedingungen for the Galley staff. For this purpose, the already installed for local refrigeration units relationship intended cooling capacity is used.
Vorzugsweise umfasst die Galley-Klimaanlage eine Preferably, the galley air conditioner includes a
Umluftkühlung. Um die Fahrzeug-Klimaanlage zu Unterstützen und damit die Temperatur innerhalb der Galley abzusenken, kann also ein zusätzlicher Kühlkreislauf, der als Forced air cooling. To support the vehicle air conditioning and thus lower the temperature within the galley, so can an additional cooling circuit, as
Umluftkühlung arbeitet, als Galley-Klimaanlage mit der beste henden Galley-Kälteanlage verbunden werden. Convection cooling works when Galley air conditioning systems are connected to the best existing Galley refrigeration system.
In einer bevorzugten Ausführungsform umfasst die In a preferred embodiment, the
Umluftkühlung einen Luftkanal, sowie einen im Luftkanal ange ordneten Wärmetauscher und einen im Luftkanal angeordneten Lüfter, wobei der Wärmetauscher über Kühlmittel-Leitungen mit der Galley-Kälteanlage verbunden ist. Bevorzugt kann die Umluftkühlung auch mehrere miteinander verbundene und/oder voneinander getrennte Luftkanäle umfassen, in welchen auch mehrere Lüfter vorgesehen sein können. In einer derartigen Ausführung kann warme Luft aus der Galley durch einen oder mehrere Luftkanäle zu einem Wärmetauscher, der von der Convection cooling an air duct, as well as a duct disposed in the air heat exchanger and a fan arranged in the air duct, wherein the heat exchanger is connected via coolant lines to the Galley refrigeration system. Preferably, the recirculation cooling can also comprise a plurality of interconnected and / or separate air ducts, in which several fans can be provided. In such an embodiment, warm air from the galley may be passed through one or more air passages to a heat exchanger provided by the
Galley-Kälteanlage der Galley versorgt wird, geleitet und dort heruntergekühlt werden. Anschließend wird die gekühlte Luft wieder in die Galley eingeleitet. Der Luftstrom wird von dem Lüfter bzw. den Lüftern erzeugt. Der Wärmetauscher kann über Kühlmittel-Leitungen beziehungsweise über Kältemittel leitungen mit der Galley-Kälteanlage verbunden sein. Galley refrigeration system of the Galley is supplied, routed and cooled down there. Then the cooled air is introduced back into the galley. The air flow is generated by the fan (s). The heat exchanger can be connected via coolant lines or refrigerant lines with the Galley refrigeration system.
Vorzugsweise ist die Galley-Klimaanlage im Bereich des Unter bodens der Galley und/oder im Unterboden der Galley angeord net. Ferner bevorzugt ist die Galley-Klimaanlage im Preferably, the Galley air conditioning in the area of the lower floor of the galley and / or in the underbody of the galley angeord net. Further preferred is the Galley air conditioning in
Unterflurbereich der Galley angeordnet. Dies hat den Vorteil, dass die Galley-Klimaanlage den freien Raum der Galley nur wenig reduziert. Die Galley-Kälteanlage kann bei dieser Lö sung auch im Unterboden der Galley angeordnet sein, so dass die aufgenommene Wärme aus dem Kältekreislauf in die Umge bung, insbesondere in eine Umgebung außerhalb des Fahrzeugs, abgegeben wird. Somit können die Transportwege für das Kühl mittel verkürzt werden, was Kosten und Platz spart und die Effizienz des Systems erhöht. Bevorzugt sind Teile der Underground area of the galley arranged. This has the advantage that the Galley air conditioning only slightly reduces the free space of the Galley. The Galley refrigeration system can also be arranged in the bottom of the galley in this solu tion, so that the heat absorbed from the refrigeration cycle in the surrounding environment, especially in an environment outside the vehicle, is delivered. Thus, the transport routes for the coolant medium can be shortened, which saves costs and space and increases the efficiency of the system. Preference is given to parts of
Galley-Klimaanlage, beispielsweise Teile eines Luftkanals, in einer Wand, einem Boden oder einer Decke der Galley angeord net . Galley air conditioning, for example, parts of an air duct, in a wall, a floor or a ceiling of the galley angeord net.

Mit anderen Worten ausgedrückt umfasst die Umluftkühlung at one end of the air duct at least one hot air intake in a floor and / or in a wall and / or in a ceiling of the galley and at another end of the air duct at least one cold air discharge in a floor and / or in a wall and / or in a Cover the galley. In other words, W locate comprises
Umluftkühlung bevorzugt an einem Ende des Luftkanals mindes tens eine Warmluftansaugeeinheit in einem Boden und/oder in einer Wand und/oder in einer Decke der Galley und an einem anderen Ende des Luftkanals mindestens eine Convection cooling preferred at one end of the air duct least one hot air intake in a floor and / or in a wall and / or in a ceiling of the Galley and at another end of the air duct at least one
Kaltluftausblaseeinheit in einem Boden und/oder in einer Wand und/oder in einer Decke der Galley. Bevorzugt ist die  Cold air blower unit in a floor and / or wall and / or galley ceiling. Preferably, the
Warmluftansaugeeinheit und/oder die Kaltluftausblaseeinheit als Lüfter oder als Gebläse ausgeführt. Warmluftansaugeeinheit and / or the Kaltluftausblaseeinheit designed as a fan or as a fan.
Da warme Luft nach oben steigt ist es regelmäßig bevorzugt und vorteilhaft, eine oder mehrere Warmluftansaugung (en) be ziehungsweise eine oder mehrere Warmluftansaugeeinheit (en) in einer Wand und/oder in einer Decke der Galley anzuordnen. Gleichzeitig kann es von Vorteil sein und ist es regelmäßig bevorzugt, eine oder mehrere Kaltluftausblasung (en) bezie hungsweise eine oder mehrere Kaltluftausblaseeinheit (en) in einem Boden der Galley anzuordnen. As warm air rises, it is usually preferred and advantageous to have one or more warm air intake (s) or one or more hot air intake units (s) to arrange a wall and / or in a ceiling of the Galley. At the same time, it may be advantageous and it is regularly preferred to arrange one or more cold air blast (s) or one or more cold blast unit (s) in a bottom of the galley.
In einer bevorzugten Ausführungsform sind mindestens eine Warmluftansaugung und mindestens eine Kaltluftausblasung räumlich, vorzugsweise um mindestens 1 Meter, getrennt vonei nander in der Galley angeordnet. Um einen Luftkurzschluss zu vermeiden sind die Warmluftansaugung und die Kaltluftausbla sung also räumlich voneinander getrennt. Die räumliche Tren nung kann sowohl vertikal als auch horizontal erfolgen. Unter räumlicher Trennung ist hier beispielsweise das Vorliegen ei nes geometrischen Abstands zwischen Warmluftansaugung und Kaltluftausblasung zu verstehen. Bevorzugt ist die mindestens eine Warmluftansaugung als Warmluftansaugeeinheit realisiert. Ferner bevorzugt ist die mindestens eine Kaltluftausblasung als Kaltluftausblaseeinheit realisiert. In a preferred embodiment, at least one hot air intake and at least one cold air discharge are arranged spatially, preferably by at least 1 meter, separated from one another in the galley. In order to avoid an air short circuit, the hot air intake and the cold air outlet are therefore spatially separated. The spatial separation can be vertical as well as horizontal. By spatial separation is meant, for example, the presence of a geometric distance between hot air intake and cold air blow-out. The at least one hot air intake is preferably realized as a hot air intake unit. Furthermore, the at least one cold air blow-out is preferably realized as a cold air blow-out unit.
In einer bevorzugten Ausführungsform ist mindestens eine Warmluftansaugung in der Galley vertikal oberhalb mindestens einer Kaltluftausblasung angeordnet. Bevorzugt bezieht sich die vorhergehend gemachte Angabe „vertikal oberhalb" dabei auf eine vom Boden der Galley ausgehend gemessene Höhe der Galley, sodass der Abstand zwischen dem Boden der Galley und der mindestens einen Kaltluftausblasung in diesem Ausfüh rungsbeispiel geringer ist als der Abstand zwischen dem Boden der Galley und der mindestens einen Warmluftansaugung. Da wärmere Luft nach oben steigt ist es regelmäßig bevorzugt und vorteilhaft, eine oder mehrere Warmluftansaugung (en) in der Galley vertikal oberhalb einer oder mehrerer Kaltluftausbla sung (en) anzuordnen. Damit wird ein effizienterer Wärmeab transport ermöglicht. In a preferred embodiment, at least one warm air intake in the galley is arranged vertically above at least one cold air blow-out. Preferably, the above statement "vertical above" refers to a height of the galley measured from the bottom of the galley so that the distance between the bottom of the galley and the at least one cold air discharge in this embodiment is less than the distance between the bottom of the galley As warmer air rises, it is often preferred and advantageous to place one or more warm air intake (s) in the galley vertically above one or more cold air outlets, thereby enabling more efficient heat transfer.
In einer bevorzugten Ausführungsform umfasst die Galley eine Steuereinheit für die Galley-Kälteanlage, die dazu eingerich tet ist, die Versorgung der lokalen Kühlstellen mit Kühlmit- tel durch die Galley-Kälteanlage gegenüber der Galley- Klimaanlage zu priorisieren . Priorität hat in dieser Ausfüh rungsform die Versorgung der Kühlstellen. Diese Funktion wird in die Steuereinheit der Galley-Kälteanlage implementiert. Somit wird sichergestellt, dass die Kühlstellen nicht unter versorgt werden, wenn beispielsweise im Sommer die Galley- Klimaanlage häufig benötigt wird. In a preferred embodiment, the galley comprises a control unit for the galley refrigeration system, which is equipped to supply the local refrigeration units with refrigeration equipment. Prioritize tel through the Galley refrigeration system to the galley air conditioner. The priority in this embodiment is the supply of the cooling points.

In einer bevorzugten Ausführungsform wird die Galley- Klimaanlage nur dann mit Kühlmittel versorgt, wenn gleichzei tig mindestens eine lokale Kühlstelle unter Teillast betrie ben wird. Ferner bevorzugt ist die Steuereinheit der Galley dazu ausgebildet, die Versorgung der Galley-Klimaanlage mit Kühlmittel nur dann zu veranlassen beziehungsweise zu bewir ken, wenn mindestens eine lokale Kühlstelle auf Teillast be trieben wird. Um zu verhindern, dass die Kühlstellen durch den zusätzlichen Kälteverbraucher unterversorgt werden, wird die Galley-Klimaanlage nur dann zugeschaltet, wenn keine oder nur eine reduzierte Kühlanforderung der Kühlstellen vorliegt. Alternativ oder zusätzlich wird die Galley-Klimaanlage nur dann zugeschaltet, wenn die Galley-Kälteanlage insgesamt im Teillastbetrieb ist. So ist es auch möglich, dass die Kühl leistung der Galley-Kälteanlage für die lokalen Kühlstellen leicht überdimensioniert ist und daher die Galley-Klimaanlage immer zumindest mit reduzierter Leistung betrieben werden kann. Es ist auch möglich, durch die Verwendung von sparsame ren Kühlstellen eine zusätzliche Kapazität der Galley- Kälteanlage für die Galley-Klimaanlage bereitzustellen. In a preferred embodiment, the Galley- air conditioning is only supplied with coolant when simultane- ously at least one local cooling point is operated under part load ben. Further preferably, the control unit of the galley is adapted to cause the supply of the galley air conditioning with coolant only to ken or to be, if at least one local cooling point will be operated at part load. In order to prevent the cooling points from being undersupplied by the additional cold consumer, the Galley air conditioning system is only switched on if there is no or only a reduced cooling requirement of the cooling points. Alternatively or additionally, the Galley air conditioning is switched on only when the Galley refrigeration system is in total part-load operation. So it is also possible that the cooling performance of the Galley refrigeration system for the local refrigeration is slightly oversized and therefore the Galley air conditioning can always be operated at least with reduced power. It is also possible to provide additional capacity of the galley refrigeration system for the galley air conditioner by the use of economical ren cooling points.
